Re: [php-weathermap] Editor won't display nodes

["Joshua Keroes" <joshua@xxxxxxxxxx>]

check.php and check-gdbug.php both run fine from the command-line.
check.php runs in the browser, too - it reports that the only feature
I'm missing from GD is an optional one:

         imagefilter    NO Non-Critical.   This is required for colorizing
                           icons. It is a special function of the
                           PHP-supplied GD library ONLY (not the external GD
                           library that you are using).

check-gdbug.php runs on the command line and all seems to be in order
there. When run in the browser, I get a white page with no HTML.

For the record, I compiled this GD, gd-2.0.35, by hand so that we had
the necessary version and features.
